Included with my system were "Special adapters for CO2 gas cartridges and canisters". So I am hoping it will fit on paintball co2. I can pick out a fancy looking one and get those refilled around the corner. If not another 10lb co2 canister from the beer store....the disposable cartridges arent so appealing. You can get the "Extendable Adapter for USA" Part # XK4310 to fit any of the NRG regulators.
I havent hooked it up yet but I will Monday. The bubble counter is glass and looks neat!
Hydor is an Italian based company and the Italians make great valves. I think the control will be superb....I will let you all know.
